> Since dropped database/table events doesn't exist in cache, currently we
> don't show the process time for drop operation in the metrics page of web UI.
> It would be great to add to new metric such as 'avg-process-time' for all the
> drop database/table events so that admins can monitor this metric to see if
> drop operations are slow.
> Generally, a drop should be fast, but it takes metastoreDdlLock_, which can
> block on HMS RPCs. So, it would be ideal to observe this operation in the web
> UI.
